Door Chime Intercom

The Door Chime Intercom operates as a regular door bell chime for everyday use, but also lets you talk to any caller before opening the door. The weather proof bell push mounts outside a door or entrance and when pressed triggers the chimer unit, (cable provided links the 2 units like normal door bell). The chimer can hang on the wall or stand on a surface. Pressing and releasing the button on the chimer unit allows you to communicate with the caller outside. Batteries supplied.
